Bug ID: 149212
Summary: Impress: Powerpoint OLE animations don't work
Product: LibreOffice
Version: 7.2.1.2 release
Hardware: All
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Impress
Assignee: [email protected]
Reporter: [email protected]
Description:
Working as a college math professor, most undergraduate textbooks come with
premade Powerpoint lecture slides from the publisher. I would like to present
these with Libre Office Impress. However, in every case the animated OLE math
objects fail to animate properly. This is consistently the case across a large
number of textbooks, authors, producers, etc., that I've tried to use (working
mostly with Pearson textbooks).
Steps to Reproduce:
1. Open the PPTX file
2. Start the slide show, proceed to slide with OLE animations, click through
(e.g., in attached file, slides 5, 7, 8, etc.)
Actual Results:
OLE objects fail to animate (in view at all times)
Expected Results:
OLE objects should animate (start invisible, then transition to visible on
click)
Reproducible: Always
User Profile Reset: No
OpenGL enabled: Yes
Additional Info:
- Note that text objects animate fine; it is only OLE objects (math images)
that do not.
- If the PPTX file is converted to ODP, the problem persists (OLE objects do
not animate)
- Although though the OLE objects don't animate, the slide still "eats up" the
expected clicks; we must click as many times as OLE objects to get to the next
slide
- Even if we delete all the animations on a slide, these "hidden" clicks
persist; we must still click as many times as objects to get to the next slide
- Trying to backtrack to the previous slide often fails on slides with OLE
animations that we tried to remove.
- I can provide an arbitrary number of publisher-made PPTX slide decks with
this problem, if desired (e.g., hundreds)
